Jean L. row-m, or rnnn'ron, new ne ADJUSTABLE PORTABLE nnnc'rmc-L onr snrronr on BASE.

To all whom it may concern: v

Be it known that I, JOHN L. Pownn, a citizen of the United States, residing at 874 Stuyvesant avenue, Trenton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in Adjustable Portable -Elect ric-Light Supports or Bases, of which the following is aspecification.

My invention relates to improvements in portableelectric light supports or bases, in which it is possible to change theangle or position of the light by movement. of the socket pipe in the main support orbase, by means of pulling the socket-pipe from'the support or base and replacing it in one of the three holes within the elongated slot, which afi'ords facilities for the proper ad justment of the light independently of the base, without the releasing or tightening of a spring by means of athulnb screw, or otherwise; p v.

A still further object of my invention, is to provide a. device which can be employed for thesnpp'ort of the lamp on a flat surface or projecting objects, which can be attached to projecting objects or pieces of furniture by means of a forward and reverse. clamp or by hanging against perpendicular objects.

The accompanying drawing illustrates my application for my invention. 5

Figure I, is aside view of he lamp. sup port or base in connection with the connecting fixture and electriclamp shade, C: Fig. 2 is the section view of the socket pipe which, is shown in connection with Fig. 1, as B: Fig. 3 is a side view of the lamp sup port or base clamped to a projecting object: Fig. l, is a, side. view of the lamp support or base clamped inanreversed position to a projecting object, thus Fig. 3 and Fig. 4,- shows a forward and reverse method of clamping: Fig. 5, is a side view of the lamp support or base attached to a perpendicular object: Fig. 6, section l, is a section view of the main support or base, representing the front section, Fig.1 7 section 2, isa. section "view of the main support or base, representing the rearsection.

Referring to'the drawing Fig. 6 section 1 and Fig. 7 section 2, designating the lamp support or base member preferably stamped or cut of spring metal, 1 and 2 as shown in Fig. G and Fig. 7 is. properly curved to constitute a forward and reverse clamping member, so as to provide two methods of Specification of Letters ram.

clamping to projecting objects or pieces of furniture, as shown in Fig. 3 and Fig. 4. 3, 1n Flg. 6 section 1 and Fig- 7 section 2,

represents the center member properly punched with the elongated slot E into which is entered the socket pipe B, as shown in Fig-1;. and forms the adjustable connecting means, designated, securing the lamp to its support or base. The socket pipe B Fig.

1,01 ustable connecting means, as shown by Din Fig. 2, is properly ridged on each side so' as to fit in the elongated slot E, Fig. 6 section 1, and Fig. 7 section 2, and may be raised or lowered in the support or base in" three different positions as shown by notches a, Z), and 0, on each side of the socket pipe B, as in Fig; 1. The socket pipe B is externally threaded and is made fast to collar of lamp socket.C. K, in Fig. 1, represents the electric'wire or cord passing through the hole F, as shown in Fig. 7, section. 2, for the purpose of obtaining suflicient slack of the electric wire or cord as designated in Fig. 1 to make easy'the adjustment of the socket pipe B. I

By the illustration in drawing it will be noticed'that the lamp may be adjusted to three (3) different positions in the support or base, relative tothe three (3) holes in the elongated slot by withdrawing the socket pipe or connecting means and reentering in one of the other of the three (3) holes, and further changes. of position of the lamp maybe obtained by raising or lowering the socket pipe or connection means and securing it in one of the three (3) notches a, b, and a, Fig. 1.

That I claim is:

1. An electric lamp support or base comprising twomembers bent in a forward and reverse curve, or otherwise, to form bearing points, and a third member of said lamp support or base slotted with'an elongated slot with three holes within said elongated slot and a socket pipe or an adjustable lamp connecting means ridged on either side and fitted with three notches, entered in one of the three holes, and made fast to the support or base by resting inone of the three notches.

' 2. An' electric lamp support or base comprising two members bent to clamp on objects in a forward and reverse manner and a third member slotted with an elongated slot with three holes within said slot with a socket pipe or connecting means entered pulling the socket pipe or connecting means from the holeswithin the elongated slot allowing the electric wire or cord to passfrom one hole to the other through the elongated slot for the-purpose of reentering the socket pipe in the hole desired;

3. An electric lamp support or base having a member slotted with an elongated slot with three holes within the slot placed at a desired distance from each other and a socket pipe or an adjustable lamp connecting means ridged-on either side fitted with three notches entered in one'or the other of 'the holes and with a fourth'hole of likei'size cient slack in same before passing through the-socket pipe or connecting means, making the withdrawal and entry of the socket pipe or connecting'means easy andwithout the loosening or tightening of a spring te'n sion or 'otheradjust'able spring controlled connecting means cooperating with the slotted member."
